Microscope Parts & SpecificationsHistorians credit the invention of the compound microscope to the Dutch spectacle maker, Zacharias Janssen, around the year 1590 (more history here). The compound microscope uses lenses and light to enlarge the image and is also called an optical or light microscope...
The transmission electron microscope is used to view thin specimens through which electrons can pass generating a projection image. The TEM is analogous in many ways to the conventional (compound) light microscope. TEM is used, among other things, to image the interior of cells (in thin sect...
In case of the retina, the safety studies consider mostly in vivo intravitreal delivery of the active compound, and the histological evaluation of the retina remains the gold standard in retinal toxicity studies; however, some complementary methods examining the retinal morphology and function are ...
riboflavin, ascorbic acid, sinapic acid,p-coumaric acid and caffeic acid are used as antioxidants. However, these complexes are quickly metabolized and eliminated from the human body. Therefore, the development of a compound or system with high antioxidant activity remains a challenge to be overcome...
With PSMA-617, we present a compound that, in addition to a PSMA inhibitor as a target vector, also contains a bisphosphonate that is established as a bone tracer and, thus, combines the advantages of PSMA targeting and bone targeting. Additionally, due to their superparamagnetic behavior, ...
cells could be enhanced to 98.1~98.7%. Moreover, the cell clusters were also able to be intercepted in the capture area of the microfluidic chip (Figure 3B–D). To ensure the accuracy of the results, the tumor cells in the cell clusters were also counted individually under a microscope. ...
